Hi
the pic 16f876a will have 2 output pins as inputs to the DC motor which is controlled using L293D H-bridge
what should I connect to protect the pic?
Re: LDR connection-help-
LDR1=5k ohm and LDR2=11.3Kohm and Im Connecting variable resisters both=10k

the problem is that im not getting enough volt from the LDR circuit to feed A0,A1 the voltage is very small...
LDR connection-help-
Hi
Im sensing the lights with 2 LDRs and using them as an ADC inputs to PIC 16F876A
the code should see the difference and gives an order to DC motor to move
right now my code is fine the only problem I have now that the LDRs read different readings but there is no...
Hi everybody
I want to Read two analogue inputs from two LDRs and display them on the LCD.
I wrote a code but the problem is :
the readings on the LCD are almost the same even if there is a difference between the lighting on the LDRs.
I used the volt meter to measure, there is a difference in...
well,,
I want to take an analog input from two sensors [LDR] and display them on the LCD ..
so I need to convert analog to digital [binary] then convert the binary to decimal to disply it on the LCD
If it is same as what you are telling me then I already have what I want :razz:
but I found...
Iam using PIC16F876A and LCD is HD44780U
I've simple things in the original code inorder to suit my PIC but still it's not working
what do you think the problem is??
the code in the first post is with the changes I made
Hi
I want some help to anderstand this code specially Initialise the LCD [LCD commands] >>watch the numbers in red how do we choose them??
I tried it on the board but nothing was displayed on the LCD what is the problem??
Hi
How do you connect LDR sensors with a PIC ??
Im writting a code to read from both LDRs and show the reading on LCD and I want to see if it's working
but I dont know how to connect the LDRs with the PIC??
